This amp even for just being a 400 w it puts out plenty of power i have it powering my 2 12" RFs and they sound way good with that 400 wats give me a bid and i'll tell you if its high enought aight NEO_MUSTANG@caraudio.com
If i were to get and am i would get a MTX 1800w it'll make those subs pound and MTX amps let you wire just about anything to them and they can take the power.
